Display dangerous Request.Form error to user

Hi,

I have a rad grid that is using EditFormSettings with a FormTemplate and in Popup mode. It is displaying a couple of items in the popup for editing purposes that are not already displayed in the grid. When a user is typing in information into these areas, I want to inform the user of any HTML tags they may mistakenly enter.

As it stands now, in testing, when HTML tags are entered into one of the text boxes and save is clicked, the form just brings back what was on the screen at submission and I record a HttpRequestValidationException in my event log. Clicking on the cancel button also exhibits this behavior as it also performs a postback and will not let me cancel the edit without removing the offensive tags.

When I debug the page through Visual Studio, I get this error message from the ScriptResource.axd: "Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500".

I cannot turn off page validation. Not an option. What I need is some way to display a message to the user that the data they have entered is incorrect and that they need to correct it to continue.

Thanks.

Grid - mini bug - Culture

Hello,

I found I quit interesting stuff with the grid... let me explain you. :)
I have a grid, with the culture="fr-FR". In the same grid, I have a date.
When I filter this column, I right click on the header and I select "Filtrer" than "Plus petit que". Here, I select my date, let's say First of april : 01/04/2011 in french culture. After this I click "Filtrer" and every thing is working.

But, when I go back to this filter, the date have changed to 04/01/2011... Not the french culture...

I found this interesting :p

In the same post I have 2 questions...
Is it possible to arrive on 'Contains' when we want to filter?
Is it possible to press Enter to apply a filter?

Thanks a lot

Jean-Yves

Is there anything analogous to IValueConverter to allow binding to a field in ViewModel that requires a transformation to render it?

I'd like to broaden this question, but the forum doesn't allow me to change the title, so I'm putting up a new posting instead here: http://www.telerik.com/community/forums/aspnet-ajax/grid/cleanest-way-to-bind-non-datatable-source-to-dropdownlist-in-code-behind.aspx

FYI, Below is my original question, which I'm still curious about, but what I really need to do is answer the broader question in the other post.

I have a couple of fields in my ViewModel that are integer representations of the Ids of a field whose name should be displayed to the user. I would like to have a GridBoundColumn to represent them in my RadGrid's view mode, but for that to work, I need there to be an intermediary class that does a conversion from the integer underlying value to the text value the user needs to see. Is there any provision for this with RadGrid, or if not, then what is the recommended practice for such a case?

Thanks!

Recurrence rule parsing, how to?

Consider the following example:

The scheduler has a recurring appointment over three days with the following duration:
09.00-10.00 wednesday
09.00-10.00 thursday
09.00-10.00 friday

How do I deny the creation of an earlier second recurring appointment? Like the one below:
09.00-10.00 monday
09.00-10.00 tuesday
09.00-10.00 wednesday (conflict not trapped)

The example provided by Telerik, "ConflictsWithOccurrences", doesn't seem to handle this particular situation.
However, the following recurring appointment is trapped as expected:
09.00-10.00 friday (conflict trapped)
09.00-10.00 saturday
09.00-10.00 sunday

Has anyone done this?

Source Code Viewer

My goal is to have a sort of "source code viewer" control. I imagine it would be something like a rad panel. The panel must have hyperlink-able numbers down the left side (ie source line numbers, like lxr or opengrok).

I was hoping something would already exist but have not found much yet. I did find this project below from 2009 but it is out of date and looks to be not maintained. Plus i have a rad dev account so i'd rather use rad controls. Is something like the project i pointed out possible and how would i get started..any samples would be great. (i dont need a directory explorer part (ie tree control)), just some type of panel with source line numbers down the left and some nice CSS would be nice.

sample
http://sourceforge.net/projects/scv/

any ideas or help would be great.

thanks
jason

Detailtables Lose Datasource on Edit / Insert

Hey guys, I have a page with a radgrid setup with one detail table under my mastertableview and two detail tables under the first detail table. If there is no data in either of the second level of detail tables there will be a gridbutton column visible to add new data. If we add or edit that data, the adjacent detailtable row loses its datasource and we no longer see the column. How can i prevent this?

Here is how my grid is setup:

RadWindowManager not updated

Hi everybody,

i have a complex scenario webapge:
A MasterPage where the RadWindowManager is declared, a default webpage where content is loaded and the content pages.
I am working with RadAjaxPanels to ajaxifiy the whole thing. I have some trouble with changing the Windows-Collection of RadWindowmanager in codebehind of the contentpage (wrapped by an Radajaxpanel). The RadWindowManager (at masterPage, no radajaxpanel) is not updated after i add a window from codebehind/contentpage.

A similar Problem is described in the following article :
"RadWindow inside a RadAjaxPanel"

I understand that the problem is because there is no PostBack and the RadWindowManager is not inside the ajaxpanel
but all the hints and solutions are going for the RadAjaxManager and not for the panels.

Basically my question is: How to update RadWindowManager declared on masterpage from an contentpage wrapped by an RadAjaxpanel

Pre Populate a RadGrid's FormTemplate

I have a grid and I'm using the grid's FormTemplate to edit and insert records into the SQL database.

<EditFormSettings EditFormType="Template">

<FormTemplate>

.....

</FormTemplate>

</EditFormSettings>

In this project that I'm working on I want to be able to select a record, take that data and populate the form WITHOUT adding the record first. Here is the button in the grid:

<telerik:GridButtonColumn

ButtonType="ImageButton"

CommandName="CopyPaste"

ConfirmDialogType="RadWindow"

ConfirmText="Copy information?"

ConfirmTitle="Copy"

ImageUrl="/Images/SmallRecycle.png"

Text="Copy"

UniqueName="CopyColumn"/>

I can easily duplicate the record in the database, but the idea is that someone enters information and the next bit of information is the same with the exception of the person tied to the record. I don't want them to have to retype the information and I don't want to write a new record and have them edit it.

Does this make sense? I'm really stuck on expanding the grid's form and filling the fields.
